NCL is a profitable base, if it wasnt we would be going the same way as MAN and downsizing. Yes NCL is a little quieter next summer but its a period of consolidation for Jet2, we have been growing every year now since our launch so its going to happen eventually where the airline needs to catch up. Jet2 are now keen to explore the charter market and the north east is one of the niche markets where people will still save year round and pay for that charter package rather than book hotac, flights etc seperate.
The LGW service is now getting popular, loads could still be better but over the weekend the laods were 100+ per flight, thats not bad really.
Also Jet2 reply heavily on onboard sales and NCL is often top selling base, i find it hard to believe that they are the lowest behind the likes of MAN BLK and even EDI, I would like to think we are maybe 2nd most profitable base.
Like 757 said, if it wasnt making money we wouldnt be here now, jet2 will chop and change things around to make money... just ask the guys in MAN!
